Marathon ramps up Droshky production

By OGJ editors HOUSTON, Sept. 8 -- Marathon Oil Corp. has ramped up production to about 45,000 boe/day net from the subsea completed Droshky development in the deepwater Gulf of Mexico.

Production from Droshky started on July 15 and the field's current net production is about 39,000 b/d of liquid hydrocarbons and 39 MMcfd of gas.

Droshky consists of four subsea completed wells on Green Canyon Block 244 about 160 miles southwest of New Orleans. The wells are in 3,000 ft of water and are tied back with two parallel 18-mile flowlines to Shell Exploration & Production Co.'s Bullwinkle platform.

Marathon noted that three of the four wells currently produce at better-than-projected levels, while equipment problems have delayed production from the fourth well. The company plans to reenter the fourth well in first-quarter 2011 to make necessary repairs. The repairs will add about $25 million to the development costs, which Marathon previously said were less than $900 million (OGJ, July 26, 2010, Newsletter).

Marathon now expects Droshky to produce at about a net 45,000 boe/d peak rate, down from the original 50,000 boe/d estimate.

Marathon holds a 100% working interest in Droshky.
